@Linkat,
There’s some commercial reason, I have one follower who has never posted on A2K and plenty others who are just work posters offering some service or other in provincial America.
If I need to start looking for a dentist, a locksmith, an accountant or whatever I’m not going to choose one in Dallas or Cranston, or even bloody London for that matter, we’ve got plenty of those here in Southampton.
That doesn’t stop them following me.
